METHOD OF LASTING SHOES.

Application fried may 2, 1924..

My present invention relates to shoes, and more particularly to an improved method of lasting the toe portion of shoes.

In my copending application, Serial No. 555,588, iiled April 19, 1922, I have described and claimed an improved method of lasting shoes so as to produce an improved McKay type of shoe that has all the desirable features of a McKay shoe as regards strength of structure while also having the advantages of a welt shoe as regards flexibility and, in the production of such shoe, I utilize the usual and ordinary component parts the ordinary upper, the ordinary insole, and the ordinary outsole. In my copending application, Serial No. 555,588, filed April 19, 1922, I have described and claimed an improved method of lasting shoes whereby there is produced an improved shoe of the McKay type and in the construction of which I employ a novel form of combined outsole and insole such as is described and claimed in my copending application, Serial No. 555,587, filed April 19, 1922. In my present invention I have described and claimed an improved process of lasting the toe portion of shoes which method is capable of being practiced on tackless McKay shoes whether the structures thereof include the ordinary insole and outsole or the novel form of combined insole and outsole such as that referred to in my copending applica.- tion.

In practicing my improved method, I preferably take the shoe after the lasting operation, as above described in my copending application, and last the toe portion thereof, temporarily fastening the upper portion of the toe with Wire, cut away the surplus lining and box toe material, and rc-last the shoe on a bed machine by means of a specially formed toe wiper, and then tack through the outsole, upper, and into the insole while the upper is held in lasting position and then U completing the construction of the shoe by withdrawing the lasting device and sewing the shoe, etc.

In the accompanying drawing I have shown, diagrammatically, views of a shoe illustrating the novel method of lasting the toe portion thereof and in the drawing.

Fig. 1 illustrates in plan View a shoe with the toey wipers and temporary lasting tacks ,in posities, and

Serial No. 710,555.

Fig. 2 is a vertical sectional elevation on the line 2-2 of Fig. 1.

Referring to the drawings, 10 designates a last on which is temporarily secured the usual and ordinary form of insole 11. The last with the insole in position thereon is placed in a lasting machine-such, for example, that shown in patent to McKay and Fairfield, No. 231,076, granted August 10, 1880. The upper 12 is placed on the last 10 and by means of the method described and claimed in my copending application, Serial No. 710,556, filed May 2, 1924, and such upper is lasted to the insole and held by temporary lasting tac-ks or by means of the wipers employed in the lasting operation. The box toe is placed in position on the shoe structure, the upper is lasted thereover and into position on the insole, and the lasted members temporarily fastened with Wire, and after the box has become set, the wire is removed and the surplus lining and box toe material is cut away. The shoe structure is now .re-lasted on a bed machine having a special form of toe wiper 13 provided with a plurality of slots 14 as shown. While the toe portion of the upper is held in position by means of the slotted blades 13, the outsole 15 is placed in position and the tacks 16 are driven through the outsole, upper, and into the insole, as shown in Fig. 2. The last 10 is now withdrawn from the shoe structure which is then processed in the usual manner to complete the same.

My improved method may be utilized on shoe structures having the usual and ordinary type of insole 11 and outsole 15 or on shoes in which there is utilized a special form of combined insole and outsole such as is described in my co-pending application, Serial No. 555,587, above referred to. rlhe resulting shoe is a McKay shoe, but is absolutcly tackless and therefore extremely ilexible and as the lasting fastenings in the ordinary McKay shoe add nothing to the strength of the structure after the sewing operation and only serve to sti'en the shoe and frequently work upward through the insole into the foot of the wearer, the shoe produced by my improved method is a decided improvement over the shoes of this type in the prior art. The resulting slices have all the advantages of the McKay type of shoe as regards strength of structure and all tlie advantages of a Welt shoe ns regjnrlls flexibility.

Having thus .Y described what I Claim as new is: he improved process of lasting' the toe portion of shoes of the McKay typo which consists in placing a box toe in position on the shoe structure.` lastingr the Hiper tliereover and into position on the insole, teniporzirily fastening the lasted members With inrention,

A n'irc removing the Wire after the bof: luis lneeoine set, Cutting away the surplus llnlng 'and box toe nniterinl, re-lzzstingf the toe portron, holding the upper in position, placing tite outsole in position and tucking through the outsole.y upper, and into the insole.

in testimony whereof, I have signed my ninna to this specification.
